There have been a lot of comments made about what disruption means and there's one area I have not seen covered: battery life.

Nokia has always performed very well in this area, but I daresay that whoever delivers a device that can be used heavily full-time for 2 or 3 days without a recharge will be truly disruptive. All other things being equal, this would cause people to change brands.

I've read over the past few years that technologies were being developed to address this need and sooner or later they have to leave the lab and get into actual use. Hopefully sooner!

EDIT: an article I wrote a while back that touches on this-- http://tabulacrypticum.wordpress.com...ile-arms-race/
